To n/ZZ whom, it may concern:

Be it known that I, JOSEPH C. SGANNELL, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Sinew-Extractors, of which the following is a specification.

This invention has for its object to provide an appliance adapted especially for use by dealers in poultry and game to break the lower joint of the legs of a fowl or bird and pull the saine forcibly from the upper joint in such manner as to remove from the fleshy parts of the legs 'thesinews which are en! gaged with the lower portions of the legs broken off by the said appliance.

The invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a. part of this specification, Figure l represents a top plan Viewof my improved. sinew-eX- tractor. Fig. 2 represents a section on line 2 2 of Fig. l. Fig. 3 represents a section on line 3 3 of Fig. 1. Fig. 4 represents a front View showing the liXed jaws. Fig. 5 represents a front View of the slide and the jaws thereon.

The same reference characters indicate .the same parts in all the figures.

In the drawings, a represents a supporting frame adapted to be attached by screws or otherwise to a bench or table and provided at one end with a raised portion a', on which are formed two pairs of upwardly-projecting jaws aga? aan?. These jaws are obliqnely arranged with reference tothe frame ct, as shown in Fig. l, and they are separated from each other by spaces of sufficient width to receive portions of the legs lof a fowl, the said spaces being too narrow to receive the feet. Each pair of jaws constitutes' a holder provided with a channel adapted to receive one of the legs. Each of said jaws is preferably a wing or ear cast uponthe portion abf the frame.

b represents a feed#screw,which is journaled in bearings at the opposite ends of the frame and extends substantially at right angles with the portion af. The portions of the frame at the opposite sides of the feed-screw and parallel therewith are formed as guides 2 2.l

c represents a slide, which is movable on Serial No. 102,751. (No model.)

`of the jawsc2 c3 is such that when theslide c is moved up to the portion a ofthe frame the jaws e2 c3 constitute extensions of the 6o jaws t2 a3, the spaces between the jaws being straight and practically continuous, so

'that the portions of vthe legs that are inserted between the Xed -jaws extend therefrom into the spaces between the jaws on the slide c. Thefeed-screw ZJ is provided with a handwheel b', having a suitable handle b2.

It willbe seen that when the lower portions of the legs of a fowl are placed in the oblique spaces between the jaws a2 a3 and c2 c3 and 7o the screw is rotatedto move the movable jaws away from the fixed jaws the oblique arrangement of the jaws will cause the portions of the legs engaged therewith to be broken between the jaws, the broken ends of the legs remaining in engagement with the movable jaws and being carried thereby away from the body portions of the legs, together with the sinews attached to the broken-off portions of the legs, saidsinews being thus pulled from 8o 4the ieshy portions of the legs.

It will be seen that this simple machine enables the operation of breaking 0E the lower ends ofthe legs and extracting the sinews to be very quickly and easily performed, relieving-the opera-tor of the severe strain and effort required to remove the sinews by mnscular power, as heretofore. The relative arrangement of the jaws must be such that when the jaws are relatively close together 9e the unbroken legs of a fowl may be readily inserted between bothV pairs of jaws, and when the distance of the jaws is increased-a bending and breaking strain will be exerted on the legs. To this end it is essential that the distance between the pairs of movable jaws be less than the distance between the pairs of fixed jaws. Itis not essential, however, that the jaws have the elongated oblique form here shown, although this form is preferable roo to any other known to me. The jaws may be of any other suitable form so long as the pairs of movable jaws are nearer together than the pairs of fixed jaws.

It is obvious that each side of the machine is an operative device which might be employed singly to break one leg at a time of a fowl.

I claim- 1. A sinew-extractor comprising two holders having channels adapted to receive one leg of a fowl, and provisions for relatively moving said holders into and out of a position substantially alining the said channels.

2. A sinew-extractor comprising two holders having channels adapted to receive one leg of a fowl, and provisions for imparting a movement of one of said holders relatively to the other in a path at an obtuse angle to the channels and into and out of a position substantially alining said channels.

3. A sinew-extractor comprising two fixed holders, two movable holders connected for operation in unison and located closer to gether than the fixed holders, said holders having channels adapted to receive the two legs of a fowl, and provisions for moving said movable holders in paths at an obtuse angle to the channels and into and out of positions substantially alining the channels.v

In testimony whereof I have affixed my signature in presence of two witnesses.
